    Abstract: The present invention relates to a method of operating circuit breakers with an intelligent electronic device (IED) wherein each phase of a multiphase power source is connected to a multiphase reactor through a circuit breaker. The method comprising, the IED: receiving measured values of voltage from a voltage transformer and current value from a current transformer for current flowing in each phase of windings of the multiphase coupled reactor; computing values of self-inductance and values of mutual inductance of the windings based on the measured values of current and voltage; estimating an instant of time for switching of a second circuit breaker on opening of a first circuit breaker based on the computed values of self inductance and mutual inductance of the windings and change in effect of mutual inductance in the windings of the multiphase reactor; and operating the second circuit breaker at the estimated instance of time.
